CLOY, verb transitive
1. Strictly, to fill; to glut. Hence, to satisfy, as the appetite; to satiate. And as the appetite when satisfied rejects additional food, hence, to fill to lothing; to surfeit.
Who can cloy the hungry edge of appetite
By bare imagination of a feast?
2. To spike up a gun; to drive a spike into the vent.
3. In farriery, to prick a horse in shoeing.
[In the two latter senses, I believe the word is Little Used, and not at all in America.]
